b$.$ Data Analysis $($Based on Custom$)$

i$.$ Based on the heights measured in $"$a$",$ calculate potential energies at C and D $.$

ii$.$ Based on the energy values from the data table, determine $U_{\text{a}\text{t}\text{a}}-K_{\text{a}\text{c}\text{c}}$ and $U_{\text{a}\text{t}\text{a}}-K_{at}.$

iii. Calculate the percent difference between

Calculated potential energy in $"i"$ at $C$ and $U$ at $-K_{\text{a}\text{t}\text{c}}.$

Calculated potential energy in $"i"$ at $D$ and $U$ a $-K_{at}.$
